This doesn't apply. 4.3.3 is about external parsed entities, as
referred to by a PERef (production [67]). We are looking at a
character reference (production CharRef, [66]).

Specifically:

No problem. The encoding of this document is iso-8859-1, and we were
assuming that the parser supports it. This is also the encoding in
which the letters '&', 'x', '0', '3', 'C', and '0' are encoded.

Not a problem. All characters contained in the entity reference are
valid in iso-8859-1. The character reference doesn't refer to an
entity; it refers to a character.

Not a problem. We have an encoding declaration.
